DE2364909A1 - Locking brake for trolley - with hinged lever pressing two vertical struts to the ground over dead point setting - Google Patents

Abstract

The trolley comprises a rear wall, and two side walls hinged on a base board complete with castors. It can be folded for easy storage and has the fourth side fitted with a simple brake. This has two vertical tubes fitted to the side of the board to locate two vertical struts linked by a horizontal cross piece and fitted with brake pads at the bottom. The cross piece is linked to a control lever by a lug eccentrically pivotted on the leverage. The brake can be fitted to a spring loaded push bar which automatically applies the brake when the operator has stopped pushing, or it can be fitted to a foot operated, or hand operated brake lever which moves over a dead point to apply the brakes.

Description

Transport trolley for piece goods

The invention relates to a trolley for piece goods, which has at least one rear wall and two pivoting side walls, a base plate and four castors. Such Weiden transport trolleys are used for the storage and transport of piece goods in warehouses and means of transport like trucks and railways.

For loading and parking the trolleys on an inclined plane and also for moving in other means of transport where deceleration forces occur, it is advisable to if means are provided by which, if necessary, an undesired rolling of the trolleys can be prevented, so that they do not run against each other and are damaged in the process.On the other hand, however, these means should be designed in such a way that that they can be easily accessed by a layperson with little construction effort are handled and take up particularly little space, so several Transport trolleys close together for the purpose of space clearance au are driving.

According to the invention this is achieved in that the trolley with two vertically arranged at a distance

Guide tubes are provided, in which two support legs stand, which are connected to each other by a cross bar that can be raised and lowered by a pivoting lever, whereby by lowering the crossbar and the support legs The rollers standing next to it are lifted off the floor so that the trolley is stable on two rollers and on two support legs that are firmly supported on the ground when

Inclined position of the base plate · By swiveling the adjusting lever in the opposite direction, the legs can be lifted like the iris, so that afterwards the trolley is back on its four Castors can be moved · It is useful if only a small amount of force is required over a longer distance to move even lift a relatively heavily loaded car! to be able to. This is possible with little structural effort, if According to one embodiment of the invention, a bracket is rotatably mounted in the cement of the transverse spar, which tab is rotatably connected to the actuating lever eccentrically to its bearing point ist · Ss this results in two lever arms of very different lengths, so that there is the possibility of using very little Force required to move the support legs into the support position by tilting the adjusting lever · Oils arrangement is preferably made so that the adjusting lever is in an angular range can be swiveled from 200 ° to 240 ° from one end position to the other, because it can be moved over two dead center positions

pivot out, within which an unintentional pivoting back would be feared.

The above-described guide tubes and the adjusting lever can be mounted on the front edge of the base plate, the adjusting lever preferably in a perpendicular parallel to a Side edge of the floor slab can be swiveled along the plane * Support legs and levers can also be used in such a case be arranged on the front of the base plate so that they can be pivoted together with this. This will, however takes up a relatively large amount of space when the base plate is swiveled up to convert the trolley into a space-saving one Storage position to be sifted · It is therefore more advantageous to use designs in which the support legs are under the rear wall of the trans » port wagons are arranged, wherein the holding tubes of the support legs are preferably firmly connected to the lower cross member of the rear wall, so that the support device is not pivoted is when the base plate is swiveled up for the purpose of space-saving storage of the transport trolley.

When the holding tubes and thus the support legs are arranged on the rear wall of the trolley, the cross bar of the support legs be connected to a rotatably mounted double lever, which is supported by an approximately vertical pull and push rod an adjusting lever is connected, which is hinged to at least one lateral support tube of the rear wall and in one The plane is pivotable, which is perpendicular to the plane of the rear wall · This gives the possibility of the support legs to be able to extend and retract by manual operation without moving

Bend over asu, because the pull and push rod can be of any length and thus the arrangement of the control lever can be of any height. There is, however, a certain disadvantage " that the adjusting lever from the back when the support legs are actuated wall or · is pivoted out of its plane · Up is thereby namely not possible with two transport trolleys standing very close to one another afterwards by actuating the adjusting lever Extending the support legs of one of the trolleys · It is therefore more advantageous, even if the support legs are arranged on the rear wall of a trolley the arrangement is made in such a way that the adjusting lever is in the plane of the rear wall is to swing back and forth. This is achieved in an embodiment which is characterized in that the transverse spar by two articulated rods with the two support legs and two further articulated rods is connected to a strut of the rear wall, the arrangement being such that when one Actuation of the adjusting lever articulated to the transverse spar a longitudinal adjustment of the transverse spar »with its height adjustment takes place · This only requires a lot of effort low forces for lifting the trolley · The adjusting lever can be in the plane of the rear wall be arranged pivotably between two stops, in which the articulated rods beyond a central dead center division are pivoted so that the trolley does not unintentionally float out of the raised position while at the same time »floating of the control lever falls back to the ground.
